Collaboration is key: Case report of suspected <i>Pseudomonas fluorescens</i> transfusion‐associated infection

Pseudomonas fluorescens is a Gram-negative rod-shaped bacterium, well-studied as an environmental microbe. It can cause opportunistic infections in humans and was implicated in previous fatal septic transfusion reactions. This report highlights the importance of both standardization in blood product culture protocols and the need for collaboration between microbiology laboratories and transfusion practitioners to optimize the recovery of potentially clinically important fastidious organisms.
